Derek Thompson and Stat News writer Matthew Herper discuss a recent surge in medical breakthroughs, including Eli Lilly’s potent triple-agonist weight-loss drug retitrutide. They analyze a major pancreatic cancer advance targeting the previously "undruggable" KRAS protein and a gene-editing therapy that permanently lowers cholesterol. The conversation explores whether these developments signal a golden age of cures, the role of AI in accelerating drug discovery, and the societal challenges of access and adherence.
